Abstract
In this research article, the spectroscopic, Transport and magnetic properties as well as the elastic parameters of cadmium cobalt ferrite nanostructures (CCFNSs) based on the chemical formula Cd0.6-gamma Co0.4+gamma/2Fe2+ gamma/2O4; gamma = 0.10, 0.15, 0.30, 0.45, were studied. These samples were synthesized using the citrates sol-gel auto combustion method through assistant citric acid and ethylene glycol as chelating agents. The properties of the CCFNSs samples were linked to the microstructure, the cation distribution and Fe2+ and Co2+ ions content (gamma). Structural, electrical, dielectric, spectroscopic, and magnetic properties were explored by XRD, SEM, LCR, Uv-Vis, FTIR, and VSM experimental techniques. XRD patterns appear formation of a cubic spinel structure for all the CCFNSs samples by the replacement of Cd2+ ions with Fe2+ and Co2+ ions. To calculation the optical parameters, The CCFNSs converted to Nano-ferrofluids by the ultrasonicate method. The increasing nature of optical bandgap in the range of 2.95-3.32 eV was observed by absorbance spectra proving Cd2+ ions replacement. The results showed a pivotal effect of added Fe2+ and Co2+ ions on the elastic, electrical, and dielectric properties mentioned in detail in the text of the manuscript. Both the saturation magnetization and the magnetic moments illustrated significant reducing trends with Fe2+ and Co2+ ions content (gamma), whereas, both the coercivity and the magnetic anisotropy constant showed opposite behavior for that.
